What reading level is Photography book?
To quickly assess the difficulty of the text, read a short excerpt:
E. Ives obtained some valuable results with an alcoholic solution of chlorophyll, the green colouring matter of leaves. Later on M. Tailfer, a French chemist, applied orthochromatism to the dry plates, by staining the previously prepared plates with eosin or erythrosin in conjunction with ammonia. The dyes still most in favour are erythrosin, pinachrome, pinacyanol, and cyanine, the two latter being chiefly used when considerable sensitiveness to red rays is demanded.
The Yellow Filter. But alt...hough by the use of suitable dyes the silver salts are rendered much more sensitive to green, yellow, and red rays, there are still a vast number of rays impinging on the plate and being absorbed by it at the opposite end of the spectrum. Dr. Kenneth Mees and Dr. Sheppard are agreed that, if no glass is used, practically two-thirds of the whole effect on the ordinary plate is due to the ultra-violet rays, and if a sheet of glass is used, about one-third. Messrs. Newton and Bull have shown that the ultra violet rays are even more effective with enclosed arc rays and wet collodion.
